The cristae of the mitochondrion greatly increase the surface area available for
Correct answer: B. the reactions of the electron transport chain
- A. the reactions of glycolysis
- B. the reactions of the electron transport chain
- C. the storage of fat
- D. the synthesis of ribosomal RNA
Explanation
The electron carriers and ATP synthase are embedded in the inner membrane, so its folding into cristae multiplies the space for oxidative phosphorylation. Glycolysis happens outside the mitochondrion in the cytoplasm, a point examiners frequently test.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
